Fluid Leaks

SYMPTOM	POSSIBLE CAUSES	ACTION
Coolant leak - External	Cooling system hose(s) damaged Expansion tank damaged Radiator damaged Casings damaged Seal(s) leaking	Refer to the appropriate service information and check the cooling system. Rectify as necessary
NOTE: This may be indicated by the emission of white smoke from the exhaust Coolant leak - Internal	Seal(s) leaking Casings damaged	Check for cross contamination of the coolant and the engine oil. Check for exhaust gases emissions through the expansion tank. Refer to the appropriate service information and check the cooling system. Rectify as necessary
Engine overheats	Insufficient coolant Insufficient oil Pressure cap fault Electric thermostat not opening Variable coolant pump failure Cooling fan failure	Check the coolant level and condition. Perform a cooling system pressure test. Rectify any leaks as necessary. Check the electric thermostat and rectify as necessary. Check the cooling fan operation - Make sure that the cooling fan rotates freely. Check for obstructions to the air flow through the radiator. Using the Jaguar Land Rover approved diagnostic equipment. Rectify as necessary
Engine takes too long to reach normal operating temperature	Electric thermostat stuck open	Check the operation of the electric thermostat. Rectify as necessary
Oil leaks - External	Seal(s) leaking Oil pipes leaking Oil filter leaking Oil cooler leaking Casings damaged Crankcase ventilation system blocked/leaking Piston ring blow-by	Clean and confirm the area of the leak. Check the visual condition of oil carrying components. Refer to the appropriate service information and check the crankcase ventilation system. Perform a compression test: Refer to: CYLINDER COMPRESSION TEST - INGENIUM I4 2.0L PETROL (G2110208)
NOTE: This may be indicated by the emission of blue smoke from the exhaust Oil leaks - Internal (leaks into the coolant or the combustion chamber)	Seal(s) leaking Casings damaged Valve guides worn Cylinder bores/piston rings worn Piston rings broken	Check for traces of oil in the coolant. Check for evidence of oil in the combustion chambers (deposits on the spark plugs, etc). Confirm oil consumption and vehicle usage with the owner/driver. Perform an oil consumption test: GO to PINPOINT TEST A .
Excessive vibration of the vehicle when stationary with the engine at idle and/or when pulling away at low speeds	Engine mounts misaligned	Complete the Powertrain Mount Alignment procedures

Crankshaft Rear Oil Seal Inspection

NOTE: Slight surface oil dampness without drops are acceptable and should not be repaired as a leak.

Remove the engine and/or transmission undershield(s) to gain access to the engine and transmission mating area (REFER to: REMOVAL AND INSTALLATION )
NOTE: Allowing the vehicle to stand for 1 hour will allow any oil to drop to the bottom of the transmission housing.
Make sure the engine is switched off and allow the vehicle to stand for 1 hour before proceeding to the next step.
NOTE:
- Make sure that any Noise, Vibration and Harshness (NVH) pads are peeled back to clean off any oil residue that may have seeped underneath.
- Make sure that the degreaser is sprayed in to the 3 breather holes between the mating faces to make sure the inside of the transmission housing is clean.
- Make sure the undershield(s) are cleaned of any oil residue.
Clean the mating faces of the engine and transmission using a suitable degreaser.

Using a suitable rag, wipe the engine and transmission, removing any remaining oil residue and degreaser.
Using a suitable leak detection spray, thoroughly coat the engine and transmission mating area.
Remove the vehicle from the ramp and allow the vehicle to idle for 10 minutes.
Increase the engine speed to 2000 Revolutions Per Minute (RPM) for 30 seconds and return to idle.
Allow the vehicle to idle for 10 minutes.
Switch off the engine and leave the vehicle to stand for 1 hour.
Place the vehicle back onto a suitable ramp and re-inspect for signs of leakage.

Crankshaft Rear Oil Seal Inspection Example Images.

The image below shows an OK condition; no visible evidence of oil. No crankshaft rear oil seal inspection test required.
